Abstract

Virtualization has recently been adopted for client devices to provide strong isolation between services and efficient manageability. Even though multimedia service is not rare for the devices, the virtual machine hosting this service is not guaranteed to receive proper scheduling support from the underlying hypervisor. The quality of multimedia service is often compromised when several virtual machines compete for computing power. This paper presents a new scheduling scheme for the hypervisor to transparently identify if the workload handles multimedia and to provide proper scheduling supports. An implementation of our scheme has shown that the virtual machine hosting a video-oriented application receives propoer CPU scheduling even when other virtual machines host CPU intensive workloads.
